FAQ CENTER
  • Port fittings are obstructing the piston

    Check thread length of port fittings.Fittings should during stroke not reach inside the housing bore.
  • Twisted or chipped gear teeth

    Check for gear binding.Actuator may not be able to be re-built and may need to be replaced.Damage could be a result of overload or shock.
  • Air in actuator

    Purge air from actuator.
     
  • Swollen seals and composite bearings caused by incompatible hydraulic fluid (standard actuators only)

    Re-build the actuator.Use fluid that is compatible with seals and bearings.Contact Chiyu Corporation for more information.
     
  • Corrosion build-up on the thrust surfaces

    Re-build the actuator.Remove all rust then polish.
  • Piston and/or shaft seal leak

    Remove the plug and the housing's valve ports.Operate the actuator through the housing ports.Conduct the internal leakage test as described in the Testing section.
  • Control or counterbalance valve has internal leak

    Disconnect hydraulic lines and bypass valve.Leave valve ports open and operate the actuator through housing ports(do not exceed operating pressure).The valve must be replaced if a steady flow of fluid is seen coming from the valve ports.
  • Low rate of fluid flow

    Inspect ports for obstructions and hydraulic lines for restrictions and leaks.
  • Insufficient torque output

    Verify correct operating pressure.Do not exceed the pressure specifications. Load may be above maximum load capacity of the actuator.

In the fast-paced, high-demand world of construction, machinery performance plays a pivotal role in ensuring project success. As equipment becomes more advanced and tasks grow more complex, one component has proven especially critical for maintaining operational efficiency and precise control: the hydraulic rotary actuator.

As robotics continues to transform industries—from advanced manufacturing and aerospace to agriculture and underwater exploration—the need for precise, powerful, and adaptable motion control systems has become more critical than ever. While electric and pneumatic actuators have been widely used in robotic systems, hydraulic rotary actuators are increasingly gaining attention for applications that demand high torque, compact size, and robust performance.

In today's industrial world, precision, speed, and reliability are essential components of successful machinery design and automation. As mechanical systems continue to evolve and become more complex, the demand for components that can provide accurate and repeatable motion increases. Among these critical components, the hydraulic rotary actuator has become a cornerstone of high-performance motion control systems.

In the vast and complex world of industrial machinery, the demand for precise, powerful, and reliable motion control solutions has never been greater. One such innovation that has transformed how industries approach rotary motion is the Hydraulic Rotary Actuator. These compact yet powerful devices offer an ideal solution for translating hydraulic energy into controlled rotary motion, especially in heavy-duty environments where traditional mechanical systems may fall short.
